How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
Returns a JSON object with: the deduplicated array of unique items, the count of unique items remaining, and the number of duplicate items that were removed, along with a schema identifier (delx/util-dedupe-list/v1).
Example use cases
Clean email list before campaign
“I have a list of email addresses collected from multiple sources and there are definitely duplicates — can you deduplicate it for me so I only send to each address once? Here's the list: ['alice@example.com', 'bob@example.com', 'alice@example.com', 'carol@example.com', 'bob@example.com']”
Deduplicate product SKU array
“Before I import these product SKUs into my inventory system, can you remove any duplicates from this list: ['SKU-001', 'SKU-002', 'SKU-001', 'SKU-003', 'SKU-002', 'SKU-004']?”
Unique tags for content pipeline
“I'm building a tag cloud and my pipeline produced a bunch of repeated tags. Can you deduplicate this tag list and tell me how many were duplicates: ['javascript', 'python', 'javascript', 'ai', 'python', 'machine-learning', 'ai']?”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/dedupe-list?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call deduplication utility with no signup required and verifiable delivery via x402. Ideal for AI agent pipelines that need quick, cheap list sanitization without spinning up custom code or a full data-processing service. Best when the list contains strings or simple scalar values.
Side effects
- Missing or empty 'items' array — likely returns an error or empty result
- Non-array input for 'items' field — schema validation failure
- Payment failure via x402 — 402 response requiring USDC payment on Base or Solana
- Network timeout for extremely large lists
- Unsupported item types (e.g. nested objects) may not deduplicate as expected
